SECTION 4: First-aid measures
4.1 Description of necessary first-aid measures
If inhaled
Fresh air, rest.
Following skin contact
Rinse skin with plenty of water or shower.
Following eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Following ingestion
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give one or two glasses of water to drink. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
SYMPTOMS: Large doses of this chemical usually induce vomiting, so acute intoxication by mouth is rare. If no pre-existing kidney damage, it is rapidly excreted. Poisoning disturbs the rhythm of heart. Large doses by mouth can cause gastrointestinal irritation, purging, weakness, and circulatory disturbances. (NTP, 1992)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
KCl poisoning can be potentially life-threatening, particularly in massive ingestions of sustained-release preparations. Profound hyperkalemia, developing over several hours, can lead to cardiac arrhythmias and death. This case series reports three episodes of sustained-release KCl poisoning in two individuals requiring whole bowel irrigation or hemodialysis. The first two episodes, in the same patient, illustrate the contrast between the successful use of decontamination versus the need for hemodialysis. The second case, in a child, illustrates the need for tertiary level pediatric expertise in managing this type of poisoning. Whole bowel irrigation with polyethylene glycol is a resource-intensive procedure most beneficial when large numbers of radio-opaque tablets are seen in the stomach. In cases where most of the tablet matter has already been absorbed, extracorporeal methods of rapidly reducing the total body burden of potassium, such as hemodialysis, might be life-saving.
